TAKATA RECALL. ON JULY 11, 2016 WE RECEIVED A RECALL LETTER FROM TOYOTA REGARDING THE NEED TO REPLACE THE PASSENGER SIDE AIRBAG. OUR LOCAL TOYOTA DEALER INFORMED US THEY DO NOT HAVE ANY REPLACEMENT PARTS A THIS TIME AND DO NOT KNOW WHEN THEY WILL BE AVAILABLE. WE CONTACT TOYOTA CORPORATE AND THEY ALSO STATED THEY DID NOT HAVE ANY PARTS AVAILABLE AND DID NOT HAVE AN ESTIMATED TIME WHEN PARTS WILL BE AVAILABLE. THE RECALL LETTER WE RECEIVED STATED THAT WE SHOULD NOT DRIVE THE VEHICLE OR AT LEAST IF WE DRIVE IT THERE SHOULD NOT BE ANYONE IN THE FRONT PASSENGER SEAT. LEAVING THE VEHICLE NON-OPERATIONAL IS NOT AN OPTION, NOR IS IT REASONABLE TO LEAVE THE FRONT PASSENGER SEAT EMPTY. TOYOTA STATES THAT SUPPLYING US WITH A LOANER VEHICLE IS NOT AN OPTION UNLESS WE WANT TO PAY FOR IT ON OUR OWN. WITH NO TIME FRAME FOR WHEN PARTS MIGHT BE AVAILABLE FOR REPAIRS WE ARE LEFT WITH DRIVING THE VEHICLE WITH AN KNOWN SAFETY ISSUE AND NO REASONABLE EXPECTATION OF COMPLETING THE REPAIRS.

VEHICLE RANDOMLY AND SUDDENLY REVS ITSELF BOTH FROM A STOPPED POSITION AND WHILE DRIVING. WHEN DRIVING DOWNHILL AND I TAKE MY FOOT OFF THE GAS THE VEHICLE WILL CONTINUE TO REV ITSELF AROUND 3000 RPM THEN WHEN I START TO TRAVEL UPHILL IT WILL DOWN SHIFT TO ABOUT 1500 RPM. THIS SEEMS BACKWARDS. TAPPING BRAKES DOES NOT CAUSE IT TO DOWNSHIFT AS NEEDED, DOES NOT SEEM RIGHT TO APPLY BRAKES AND VEHICLE CONTINUES TO REV ITSELF HIGHER NOR DOES IT SEEM RIGHT TO TAKE FOOT COMPLETELY OFF THE GAS PEDAL AND THE VEHICLE CONTINUES TO REV UP. THE ONLY WAY TO GET IT TO IDLE IS TO APPLY PRESSURE TO THE GAS PEDAL AND SPEED UP WHICH IS DANGEROUS WHEN ALREADY GOING DOWNHILL. WHEN TRAVELLING IN A PARKING LOT IT REV ITSELF UP AND WILL JUMP FORWARD. FROM A STOPPED POSITION SUCH AS IN MY DRIVEWAY OR AT A STOPLIGHT I WILL PRESS THE GAS AND IT WILL NOT GO INTO DRIVE BUT IT WILL REV UP TO ABOUT 3500. NONE OF THESE ISSUES CAN BE DUPLICATED BY THE DEALERSHIP OF COURSE. AT ONE POINT THEY FINALLY CHANGED OUT SOME TYPE OF COMPONENT IN SHIFT MECHANISM AND THAT WORKED FOR ABOUT A WEEK THEN THE PROBLEM STARTED AGAIN. THERE IS NEVER A CODE INDICATING THERE IS ANYTHING WRONG ALTHOUGH THE TRAC LIGHT WILL RANDOMLY COME ON AND NOT TURN OFF. I HAVE BEEN DRIVING FOR 30 YEARS AND KNOW WHEN A CAR IS NOT DRIVING PROPERLY. THIS IS MY 2D 4 RUNNER. FIRST WAS AN '03 AND HAD SIMILAR ISSUES BUT SINCE WAS LESS THAN A YEAR OLD I FINALLY CONVINCED THE DEALERSHIP TO REPLACE THE TRANSMISSION AT TOYOTAS COST. THIS ONE WAS PURCHASED USED AND HAS MORE MILES ON IT BUT IT SEEMS TO BE THE SAME PROBLEMS AS MY ORIGINAL. THE ONLY WAY I HAVE BEEN ABLE TO GET DEALERSHIP TO BELIEVE ME IS TO ASK THE SERVICE MANAGER TO DRIVE MY VEHICLE FOR SEVERAL DAYS THEN THEY ARE LIKE OH I SEE WHAT YOU MEAN. ANOTHER INCIDENT WAS ON A SNOW PACKED ROAD. TRAVELLING 10MPH WHEN THE VEHICLE DOWNSHIFTED I LOST CONTROL.

NOT A GOOD SITUATION TO BE FAR FROM HOME WITH A VEHICLE STUCK IN 4 LO. I TOOK IT TO A TRANSMISSION SPECIALIST. THEY COULD FIND NOTHING WRONG AND SAID THE CODE INDICATED A "RANGE PROBLEM" WITH THE TRANSMISSION AND THEY RESET THE CODES. NOW THE 4 LO LIGHT IS FLASHING AGAIN, TRAC OFF AND CHECK ENGINE LIGHTS ARE ON. GOING BACK TO TOYOTA. HOPE THEY CAN FIGURE OUT WHAT THE PROBLEM IS.

TOOK IT TO THE LOCAL DEALERSHIP IN MARCH 2015 WHICH FOUND THE TAIL LIGHT HAS AN "EXCESSIVELY HIGH VOLTAGE" WHICH CONTINUES TO BURN OUT THE BULB. THE REPAIR WAS TO REPLACE THE ENTIRE DRIVER'S SIDE TAIL LIGHT ASSEMBLY AT A COST OF $290. THERE WAS NO RECALL OR TSB SO REPAIRS CAME OUT OF POCKET. THIS IS AN EXTREMELY DANGEROUS CONDITION THAT COULD HAVE RESULTED IN A FIRE. THIS VEHICLE IS DESIGNED TO HOLD MULTIPLE PASSENGERS, OF WHICH MY TWO CHILDREN OFTEN ACCOMPANY ME. I'M NOT SURE HOW SAFE IT IS TO DRIVE EVEN AFTER THE REPAIR. *TR

I BROUGHT MY 4RUNNER IN TO A REPUTABLE TIRE STORE FOR A ROUTINE TIRE ROTATION. THE TECHNICIAN SNAPPED A LUG STUD. I THEN HAD TO TAKE THE TRUCK TO A SEPARATE AUTOMOTIVE REPAIR SHOP TO HAVE THE STUD REPLACED. I ATTRIBUTED THE INCIDENT TO A POORLY TRAINED TECHNICIAN. RECENTLY, I BROUGHT THE TRUCK IN FOR ANOTHER TIRE ROTATION. AGAIN, THE TECHNICIAN BROKE A LUG STUD. THE MANAGER INSISTED THAT THEY ALWAYS USE A TORQUE STICK SET TO FACTORY SPECIFICATIONS AND THAT THERE WAS NO TECHNICIAN ERROR. HE ALSO SAID THAT THE SHOP HAD SEEN THIS PROBLEM WITH OTHER TOYOTA TRUCKS OF THIS VINTAGE. I THEN TOOK THE TRUCK TO THE DEALER AND, NOT SURPRISINGLY, THEY SAID THE TIRE SHOP WAS AT FAULT. THEY SAID ALL STUDS SHOULD BE EVALUATED. IN DOING SO THEY NOTED THAT 8 STUDS WERE DAMAGED AND SHOULD BE REPLACED FOR A TOTAL COST OVER $400.00. THEY REFUSED TO ACKNOWLEDGE ANY CULPABILITY, SAID THE DAMAGE WAS NOT WARRANTABLE, AND I PAID THE FULL PRICE FOR REPLACEMENT. LOOKING ON THE INTERNET I HAVE FOUND MULTIPLE COMPLAINTS ABOUT LUG STUDS BREAKING ON 2010-2012 4RUNNERS AND TACOMAS. HERE IS A WELL-DOCUMENTED EXAMPLE: HTTP://WWW.ARTSAUTOMOTIVE.COM/PUBLICATIONS/2-EXPLANATORY/170-2010-4RUNNER-LUG-STUD-PROBLEM I PREVIOUSLY OWNED A 1990 4RUNNER FOR 20 YEARS AND NEVER HAD A PROBLEM WITH LUG STUDS BEING BROKEN OR DAMAGED. IN FACT, I HAVE NEVER HAD A LUG STUD BROKEN OR DAMAGED ON ANY CAR I HAVE EVER OWNED. I BELIEVE THE 2010 4RUNNER LUG STUDS ARE DEFECTIVE FROM THE FACTORY AND TOYOTA WILL NOT OWN UP TO THIS FACT. *TR

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
